android - 更新位于 AlertDialog 中的列表视图项

Question

我在扩展 DialogFragment 的类中构建了一个 AlertDialog：

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    super.onCreateDialog(savedInstanceState);

    Intent locationTypesIntent = new Intent(getActivity(), LocationTypesRetrieverService.class);
    getActivity().getApplicationContext().startService(locationTypesIntent);

    itemsOnList = new CharSequence[noOfItems];
    itemsChecked = new boolean[noOfItems];
    for(int i=0;i<noOfItems;i++)
    {
        itemsOnList[i] = "Location " + i;
        itemsChecked[i] = true;
    }

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setTitle("Filter locations")
           .setMultiChoiceItems(itemsOnList, itemsChecked, 
                   new DialogInterface.OnMultiChoiceClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                        System.out.println("clicked choice");                           
                    }
                }
     );
    createdAlertDialog = builder.create();
    return createdAlertDialog;
}

然后我尝试在 AlertDialog 中检索列表，并更改适配器，以更新显示的项目：

public void updateOptions(String[] optionsArray)
{
    ListView list = createdAlertDialog.getListView();
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity().getApplicationContext(),list.getId(),optionsArray);
    list.setAdapter(adapter);
    //list.invalidate();
}

我收到一个错误：

E/AndroidRuntime(9401): android.content.res.Resources$NotFoundException: 资源 ID #0x1020403 类型 #0x12 无效

到底是怎么回事？？？

Answer 1

移动这一行：

list.setAdapter(adapter);

在onViewCreated您的片段的方法下：

public void onViewCreated(View view,Bundle savedInstanceState){
    //...

    list.setAdapter(mAdapter);
}
